254 VOLUTA. VOLUTE. 



13. Voluta Bullaoides. Bulla Volute. 

 Montagu, pi. 30. f. 4. 



Shell oval, pale horn-color, with a purplish-brown tinge 

 at the tip, which is most minute : spires eleven or twelve, 

 flat, not regularly divided hy a line of separation, but folding 

 over each other and leaving the edge abrupt ; the larger 

 volution covering three-fourths of the shell, the others very 

 small, the terminal ones suddenly and abruptly decreasing 

 in size : aperture contracted, the outer-lip reaching above 

 half-way up the shell ; pillar-lip quite smooth, without fold 

 or tooth, but the lower part of the outer-lip makes a short 

 curl, enters the aperture, and becomes a strong ridge on 

 the pillar, and by its flexure forms a sort of canal or gutter : 

 length three-eighths of an inch ; breadth about half its 

 length. 



Found in the Portland museum. 



14. Voluta heteroclyta. Reversed Volute. 

 Laskey, Wern. Soc. I pi. 8. f. 12. 



Shell white, glossy, slightly tapering to an obtuse point, 

 veined like ivory in a longitudinal direction ; spires eight 

 or nine, reversed, the larger volution covering two-thirds of 

 the shell : aperture narrow-oval, not quite reaching half- 

 way up ; the pillar with a single fold : length a quarter of 

 an inch ; breadth a third of its length. 



On the Dunbar coast : very rare.
